6.5 Interpreting Test Results
Refer to the following sections for information specific to each test.
6.5.1 Aspirin Test Results
The sample result (Figure 6-14) for the Aspirin Test is interpreted based on the rate of platelet
aggregation measured and is reported in Aspirin Reaction Units (ARU).
Figure 6‑14 Aspirin Test Results
Interpretation of results is based on the following assigned cutoffs: Results ≥ 550 ARU implies
platelet dysfunction consistent with aspirin has not been detected. Results < 550 ARU implies platelet
dysfunction consistent with aspirin has been detected. Results should be interpreted in conjunction with
other laboratory and clinical data available to the clinician. The result may be printed by pressing the
Print key, if your instrument has an attached printer. Press the Next key to return to the Main
Menu. Press the Retrieve key to retrieve past test results. Refer to Chapter 5, Quality Controls for
more information on retrieving results.
6.5.2 PRUTest Results
The PRUTest reports patient results in P2Y12 Reaction Units (Figure 6-15). P2Y12 Reaction Units
(PRU) report the amount of P2Y12 receptor mediated aggregation specific to the platelet and are
calculated as a function of the rate and extent of platelet aggregation in the ADP channel.
